Retrofitting a USB socket in the motorhome
Charging USB devices via the on-board power supply of the camping vehicle
These days, nothing works without USB connections. However, there are often not enough connections for cameras, mobile phones and tablets in motorhomes and caravans. That's why you can read here how to easily retrofit a USB socket.

Functions of the new USB sockets
We decided to install two USB sockets in the cupboard next to the door. There are four connections to charge all electrical devices at the same time.
- Overall dimension 59.5 by 59.5 mm
- single frame
- two USB sockets type A
- Input voltage: 12 V
- Output voltage: DC 5 V (+/- 5 %, 2x2.5 A)
Installation report: USB socket
The small cupboard between the entry door and the bed is perfect for the new USB sockets. There are several reasons for this:
- A central location that can be accessed from anywhere in the motorhome.
- The cabinet also serves as a shelf for devices to be charged.
- There is already electricity here.
- You can easily work on the wiring from below.
The pulled-out drawer makes it easy to reach the power cables and work on them.
The new USB sockets measure 59.5 by 59.5 millimetres. To ensure that the distance of the sockets to each other and to the wall is the same, everything must be precisely measured beforehand.
Make sure you use sharp tools and work carefully. This is the only way to achieve good results.
To prevent the top of the cupboard from splintering when we drill into it, we masked the surface with masking tape.
We then remove the masking tape and the sawdust and clean the surface again.
Then insert the sockets and screw them in place.
To connect the cables, the wires are stripped with the help of a wire stripper. Be careful not to cut the insulation deeper than necessary to remove the insulation layer, so as not to damage the electrical conductors.
To prevent short circuits or shearing off of the conductor, wire end ferrules are used.
Then the cables are connected according to the colour scheme in the motorhome (follow the instructions for use).
Finally, the two sockets get cover frames with hinged covers.
Conclusion: small effort, big benefit
By installing the USB sockets, we have upgraded the motorhome. It is also very practical to be able to charge all devices centrally now. If you enjoy technology, you can do the installation yourself without any problems.
